The Premier League say they “understand and respect the strength of feeling” but said “the actions of a minority seen today have no justification”.
In a statement, the Premier League said: “Following the security breach at Old Trafford, the Manchester United vs. Liverpool game has been postponed.
This is a collective decision from the police, both clubs, the Premier League and local authorities.
“The security and safety of everyone at Old Trafford remains of paramount importance. We understand and respect the strength of feeling but condemn all acts of violence, criminal damage and trespass, especially given the associated COVID-19 breaches.
Fans have many channels by which to make their views known, but the actions of a minority seen today have no justification.
“We sympathise with the police and stewards who had to deal with a dangerous situation that should have no place in football.
“The rearrangement of the fixture will be communicated in due course.”
